MD-3

High resolution, multiband dynamics processing
has been a trademark of TC Electronic for more
than a decade. Splitting audio into frequency
bands before expanding or compressing, tre-
mendously helps fight breathing and spectral
intermodulation artifacts. Our algorithms are de-
signed with the headroom to do so without in-
troducing split- and recombination filter anoma-
lies, and can be used for level optimization, mix
assistance or discreet spectral balancing as re-
quired.

MD3 is a refinement of the legendary MD2  dy-
namics processor from M5000. It uses a mul-
tiband, 48 bit resolution structure, and offers a
3-band Compressor, Expander, 4-band para-
metric Equalizer and Limiter in one powerful
algorithm. MD3 can be configured for stereo
or dual mono processing, and used on single
sources as well as composite stereo mixes.

Alternatively, stereo material may be processed
in the MS domain, or MD3 may take in MS sig-
nals and convert them to stereo with processing
taking place in either the LR or MS domain. The
multiband section has the advantage of adjust-
able look-ahead delay for gentle processing of
transients, while the Limiter uses its own over-
shoot proof micro-delay to prevent output sam-
ples above the threshold set.

MD-3 is offered as an option via license. Please
read the appendix describing license options
and how to obtain codes. The MD-3 will run at
Sample Rates (32, 44.1, 48, 88.2 or 96 kHz)

Signal flow through the algorithm is as follows:

– In level
– MS Encoder
– EQ
– Normalizer
– Softclipper
– Expander / Compressor
– MS Decoder
– Softclipper
– Limiter
– Out level
– Fader

The MD-3 algorithm occupies:

– @ Normal Sample Rate: 1/4 DSP Resource

– @ Double Sample Rate: 1/4 DSP Resource

The inputs and outputs of this algorithm are dis-
tributed as follows:

Off to 40 dB: in 3 dB steps
-40 dB to 0 dB in 0.5 dB steps
Sets the Input level for the two Input channels

Input Mode
Range:
Stereo, Dual Mono, MS Linked, MS Unlink.

Stereo
In Stereo Mode the Expander/Compressor sec-
tion of the algorithm uses one common Side-
Chain for both Left and Right channels and the
EQ section is linked.
